If you cotton to honey, you'll want to head over to Briggs Hall tomorrow (Saturday, April 17) during the 96th annual UC Davis Picnic Day.

You can sample cotton honey, as well as five other flavors, from 11 a.m. to 4 p.m.

Extension apiculturist Eric Mussen of the UC Davis Department of Entomology faculty will be offering samples of these honeys: orange blossom, eucalyptus, raspberry, meadowfoam (a vernal-pool flower that is grown commercially in Oregon for oil), starthistle, and cotton.

You'll get six toothpicks, one for each container of honey. You'll taste the exquisite meadowfoam, the exotic raspberry, and then what some folks say is the "best-of-the-best" honey--starthistle. Bees make this from an invasive, exotic weed that agriculturists hate. Our tiny winged agricultural workers love it.

And then you'll taste cotton. Hint: it's a light-colored variety of honey.

If you have a question about honey bees, including colony collapse disorder, ask away.

At Mussen's booth, you can also taste "Honey Lovers," the fruit chews that Gimbal's Fine Candies makes with real honey. Gimbal's, located in San Francisco, is donating 5 percent of the proceeds from the sale of Honey Lovers to UC Davis honey bee research.

These sweet treats at Briggs Hall are free.

Here's what else the entomologists are planning at Briggs Hall and at the Bohart Museum of Entomology.

You'll see racing cockroaches, termite trails, Maggot Art, kissing bugs, fleas, ticks, walnut twig beetles and the like, and you can take home some free ladybugs (lady beetles) from the statewide UC Integrated Pest Management Program.

When some folks think of a honey bee, they immediately think of stings.

Not pollination, not honey, not colony collapse disorder, but stings.

To beekeepers, stings are a minor irritation, or perhaps not an irritation at all. It's just something that happens in an occupation. "It's like grease on a mechanic's hands," says bee breeder-geneticist Susan Cobey, manager of the Harry H. Laidlaw Jr. Honey Bee Facility at the University of California, Davis.

Or, I imagine, like flour on a baker, dirt on a gardener or sweat on an athlete.

It happens.

Yesterday, when Extension Apiculturist Eric Mussen of the UC Davis Department of Entomology faculty was opening a hive at the UC Davis apiary, a bee landed on his wrist.

"Bee on my wrist," he said, knowing I had my macro lens at the ready.

The bee, defending her hive, did what a good guard does--she stung him. When that happens, you scrape the stinger off with your fingernail so the barbed stinger with its attached venom sac doesn't continue to pump venom.

When a worker bee stings and pulls away from her victim, part of her anatomy pulls away, too. She dies, often within minutes.

What you usually see is only the stinger. Not this time. The camera lens caught the barbed stinger and the stretched tissue.

We're glad to see that three noted entomologists at the University of California, Davis, received distinguished awards in their fields at the 94th annual meeting of the Pacific Branch, Entomological Society of America (PBESA) on April 13 in Boise, Idaho.

This year marked one of the most celebrated years of professional recognition for UC Davis faculty at a PBESA meeting. (A fourth faculty member, chemical ecologist Walter Leal, received the prestigious C. W. Woodworth Award on Monday, April 12.)

As regional award winners, Parrella, Zalom and Godfrey will now advance to the national ESA awards competition. The national meeting is set Dec. 12-15 in San Diego.

You'll often see Michael Parrella working on administrative duties, making presentations or conducting research; you'll see Larry Godfrey chasing pests in the rice and cotton fields; and you'll see Frank Zalom working on scores of integrated pest management projects, from local to global. All three work closely with their graduate students, the next generation of entomologists.

Indeed, their accomplishments could fill multiple books.

You can read more about their accomplishments on the UC Davis Department of Entomology Web site.

Just a few of the comments they received:

Michael Parrella“In his 30-year career, Dr. Parrella has developed an internationally recognized program focused on advancing integrated pest management and biological control for the floriculture and nursery industry,” said James Carey, professor of entomology at UC Davis and chair of the department’s awards committee.

“This industry, once dominated by chemical control strategies, now regularly uses the tenets of IPM, and many growers routinely use biological control,” said Carey, who nominated Parrella for the award. “His training of graduate students and postdoctoral scientists and the extraordinary effort to translate research into practice puts Dr. Parrella in a class by himself. He has accomplished this while shouldering an enormous administrative load.”

Larry GodfreyHe focuses his program on the IPM of insect and mite pests of field crops and vegetable crops, particularly pests of cotton and rice. His work extends globally. “Given the diversity of agriculture in California, this is a vast undertaking and Dr. Godfrey has made significant contributions in approximately 15 different crops during his 19-year tenure in this position,” said Parrella, who nominated him for the award. “This incredible diversity of effort and accomplishment puts Dr. Godfrey in a class by himself..."

Godfrey works closely with the county-based UC Cooperative Extension advisors and pest control advisors, industry representatives, and growers. His expertise includes sucking insects (cotton aphids and silverleaf whiteflies) on San Joaquin Valley cotton and pests of rice, including the rice water weevil.

Frank ZalomIPM specialist Zalom is not only a professor of entomology but an Extension agronomist and an entomologist in the Agricultural Experiment Station. He's "one of the most influential scientists in the development and implementation of IPM policy and practices in the United States and the world, through his numerous and continuing contributions as a leader, director, and organizer,” said colleague Jocelyn Millar, an entomology professor at UC Riverside who nominated him for the award.

Zalom, who directed the statewide UC IPM Program for 16 years (among other responsibilities) is known for his “truly extraordinary record of achievement and service to IPM extending over several decades,” Millar said.

When the C. W. Woodworth Award, the highest award offered by the Pacific Branch of the Entomological Society of America (PBESA) was awarded this week to chemical ecologist Walter Leal, professor of entomology at UC Davis, it linked two entomology trailblazers.

Woodworth (1865-1940), considered the founder of both the UC Berkeley and UC Davis departments of entomology, is an entomological legend. Leal is a worldwide authority on the relatively new field of insect communication and olfaction.

“Because of his deep and meaningful body of work over the last 10 years, Dr. Walter S. Leal of UC Davis is a wonderful selection as the 42nd recipient of the C.W. Woodworth Award," said Holden, who is writing a book on his great-grandfather. "His research into the detailed neuronal responses in mosquitoes to DEET and nonanal has been particularly impressive. His research has improved our knowledge of mosquito behavior in the presence of these two compounds, both of which are central in the efforts to understand and control mosquito-borne illness."

Both Leal and Holden are closely connected to UC Davis. Leal joined the Department of Entomology 10 years ago and served as department chair. Holden received his bachelor of science degree in electrical engineering from UC Davis in 1981.

If you look on Wikipedia, you can glean information about the remarkable career of C. W. Woodworth and the award. His great-grandson researched and wrote the entries.

If you look on the UC Davis entomology Web site, you can read about the remarkable work of Walter Leal.

Two trailblazers.

The California native wildflower (Calandrinia ciliatais) from the purslane family (Portulacaceae) blooms from February through May.

Farmers who grow baby spinach and other crops consider it a weed. Honey bees don't. It's a food source that helps them build up their hives in the spring.

If you ever see a patch of redmaids, you'll surely see bees foraging among the bright blossoms.

There's a patch on Hutchison Drive, near the Harry H. Laidlaw Jr. Honey Bee Research Facility at the University of California, Davis. New World Carniolan bees reared by bee breeder-geneticist Susan Cobey, manager of the Laidlaw facility, can be seen foraging there.
